Reflective materials such as Teflon and Enhanced Specular Reflector are commonly used to maximize light collection in scintillator-based radiation detection systems. While effective, in most cases, the spatial information carried by the light is diminished or lost entirely. Retroreflectors, in contrast, better preserve the spatial information and have been shown to improve the localization performance of such systems. In this work, the relative retroreflectivity of a selection of commercial retroreflective tapes and their performance impact when coupled to a plastic scintillator are reported. We demonstrate improved localization performance with some tapes compared to Teflon and black paint.

诸如聚四氟乙烯和增强镜面反射器之类的反射材料通常用于使基于闪烁体的辐射检测系统中的光收集最大化。虽然有效，但在大多数情况下，灯光所携带的空间信息会减少或完全消失。相比之下，后向反射器可以更好地保留空间信息，并且已被证明可以改善此类系统的定位性能。在这项工作中，报道了选择的商业逆向反射带的相对逆向反射性及其与塑料闪烁体耦合时的性能影响。与聚四氟乙烯和黑色涂料相比，我们证明了某些胶带具有更高的定位性能。
